Astarotte's Toy

Succubi are a race of beings who survive by having a harem of men from which they can suck 'life essence' from. However, Astarotte Ygvar, the crown princess, hates men. Under relentless pressure from Judit, her chief of staff, to grow up and start building her harem, she agrees to start but only with a human male. In the Creature World, humans are considered mythical creatures, with none having been seen in a thousand years. To her dismay, Judit manages to travel to the human realm and return with a 23 year old human male named Naoya Tōhara, who accepts the offer to found Astarotte's harem. « read less

Naoya brings his ten year old daughter, Asuha, to the Creature World. Upon learning their ages, Astarotte grows upset since it would mean he had sex when he was twelve, though Asuha is quick to jump to Naoya's defense. Wanting to apologise to her, Asuha enrols into Astarotte's school, where she makes some new friends, Mist, Yuna and Lucca, who mention they haven't had the courage to be friends with Astarotte. As Asuha makes up with Astarotte, rumours spread about a 'human male' on campus, which turns out to be a rampaging llama from a zoo. As it goes wild, Mist, Yuna and Lucca step in to defend Astarotte before Naoya manages to calm it down. Afterwards, Astarotte manages to make friends with the other girls, who nickname her 'Lotte'. « read less

Naoya feels conflicted by the appearance of Mercelida, who three years after their chance fling left Asuha with him and disappeared, with Mercelida immediately running off before listening to what Naoya has to say. Judit reveals to Naoya that Mercelida is the queen, making Asuha and Astarotte half-sisters, and asks him to keep it a secret from Astarotte. Wanting to speak with Mercelida, Naoya and Asuha sneak into the palace dressed as maids. They are discovered by one of the queen's servants but is coincidentally chosen to be an escort based on Mercelida's requests. Upon meeting her, Naoya gives his thanks to Mercelida for bringing Asuha into his life. As Naoya talks with Mercelida, it is revealed she hid Asuha in the human realm to avoid the same battle against sisters for the throne that she faced. Noticing Astarotte is still downhearted, Naoya asks Mercelida to visit her class for the day, making it a day where everyone's parents could visit. Afterwards, Astarotte and Mercelida manage to reconcile with each other. « read less

Naoya travels to the human world in order to replenish Astarotte's magic so that she can return. However, Astarotte is still mad at him and tries to lock him out of his house, though this ultimately fails. After making up with her, Naoya kisses Astarotte on her forehead, allowing her to regain her magic and return to the demon world. As Naoya takes Astarotte to an amusement park as way of apology, Elika decides to take Asuha with her to the same park. To test her alleged 'adulthood', Elika suggests Astarotte go inside a haunted house, where she becomes so scared that she wets herself. As she becomes upset about it, Naoya reveals he didn't stop wetting the bed until he was 12. Upon returning home, they find Ingrid has moved her tower closer to the castle and become shocked when Ingrid suddenly kisses Naoya on the lips. « read less

Astarotte and the others go to a private beach for some fun. Mercelida is also visiting another part of the beach and ends up meeting with Astarotte, hearing about how she's becoming friends with Asuha. After they part ways, Naoya catches a fever and seems to be uncomfortable around a 'certain area'. As Astalotte and her friends work on some get well food with help from Sigurð, Judit pressures Naoya to make more progress with the sexual nature of his relationship with Astarotte. « read less

Astarotte gets a red clover-shaped mark on her back, allegedly a sign that she is becoming an adult, and Judit tries to push Naoya into fulfilling his job description. As Judit later finds out it is not the same mark, but instead related to the leaves on the World Tree turning red, Naoya and Asuha start feeling weird. Ini theorises that the magical balance between worlds is destabilising and the World Tree is attempting to eliminate foreign objects from the Demon World, namely Naoya and Asuha. Soon, Naoya and Asuha become unable to hear the others and vice versa, and they also discover the entries in Asuha's diary are disappearing. With Astarotte potentially at risk from the World Tree as well, Naoya and Asuha decide they need to return to the Human World. The castle holds a farewell party, where Astarotte exchanges gifts with Asuha before asking Naoya on a date. « read less
